Description: The Slow Digestibility Index (SDI) is a tool that helps
        users evaluate the slow-digestion properties of crops or food
        matrices by combining multiple factors into a single score. It
        considers parameters related to starch composition [total
        starch (TS), amylose/amylopectin ratio (Aratio), total amylose
        content (TAC), and total amylopectin content (TAPC)], starch
        digestibility [rapidly digestible starch (RDS), slowly
        digestible starch (SDS) and resistant starch (RS)], structural
        properties [relative crystallinity (RC)], non-starch components
        [total protein, total oil content (TOC), and total phenolic
        content (TPC)], and pasting behaviour [peak viscosity (PV),
        pasting temperature (PT), holding strength (HS), and final
        viscosity (FV)].The SDI is flexible and allows users to
        calculate the index using all parameters or only selected ones,
        depending on the data available. Users can also compute a
        starch-based SDI (using only starch-related parameters) or a
        principal component analysis (PCA)-based SDI, where weights are
        determined automatically from the data. Thus, the SDI provides
        a simple way to compare and rank crops or food samples based on
        their slow digestion potential. The package implements
        SDI(),starchSDI(), genSDI(), scoreSDI(), and pcaSDI() for
        estimating slow digestibility index using predefined weighted
        TOPSIS, starch-specific TOPSIS, user-defined weighted TOPSIS,
        score-based normalization, and PCA based approaches,
        respectively. The package has been developed using the
        algorithm of Pandey et al. (2026)
